I can always take a look at your save file if you want but in all cases, you've basically missed a quest somewhere. Complete all other quests up to day 68 and "part two" of the game will unlock.
How do I send you my save file.. I checked my quests again and the only ones I dont have up to 68 are Nina's,mia, dr.ramaroy and stella, and Lisa's but when I go to do them nothing happens for example Lisa's quest is to go to hospital and get an std test but I go and dosnt give me the option to get the test that one is day 55 and rest I have up to 59 and 60
Stacy is also somewhere missing from that list, but I'm guessing you haven't unlocked the laboratory yet or something along the lines. Generally speaking, it's pretty easy to trigger stuff so you're missing a quest somewhere which might be blocking certain progress. Alternatively, you can just visit a bunch of locations, talk to characters and see if that works.
If you're really lost I can check out what's up for which you have to join Discord and drop a save file where either I or others will help and see what's on going on.
They can be found here:
PC: C:\Users\YourWindowsUserName\AppData\Roaming\RenPy\Lewd Town Adventures
Android: SD:/Android/data/com.{gamename}.program/files/saves Alternatively, you can use the file manager to find the correct save map where the Renpy save files belong.
